US Patent 9296263 Smart active tyre pressure optimising system

Smart Active Tire Pressure Optimizing System is a highly time sensitive design and technique that acts instantaneously to sense and control the tire pressure particularly during imminent/inevitable critical driving situations to reduce emergency and high speed breaking distance, mitigates loss of traction, hydroplaning, roll over, loss of stability, over and under steering, brake-failure, loss of control due to puncture through real-time sensing, perform context aware computing and directing Tire Pressure Control Units to actively control the tire pressure in right time with right pressure on right tires thereby instantly controlling footprint and sidewall deformation rate to enhance, traction and stability simultaneously sustaining drivability/steer-ability and restore/optimize to pre-set tire pressure value immediately after overcoming critical situation for further safe and comfortable driving. Other aspects are controlling tire temperature according to environmental temperature, moisture and humidity to enhance traction and vary tire pressure according to driving modes like comfort, standard, sports etcetera.
